Folders that have not been given secret settings by the management means Characterized in that it to function as a folder list display means for displaying the body in the folder list screen.

The e-mail client program, the processing equipment, to manage an address book that registered the address of the person you want to send and receive messages, and address management means for applying a secret set to the address specified by the user, accepted the initial screen display means If the password is correct, all addresses managed by the address management means are displayed on the address list screen. If the password received by the initial screen display means is incorrect, the secret setting is assigned by the address management means. you so as to function as an address list display means for displaying the not address only the address list screen.

The second viewpoint of the present invention, the mail client program a mobile telephone terminal apparatus equipped with, at the start of the mail client program, to display the initial screen password input field is provided, a password by the user An initial screen display unit that receives the input of the message, and a message management unit that accommodates and manages the transmitted and received messages in a folder and assigns a secret setting to the folder specified by the user. If the password received by the initial screen display unit is correct, all folders managed by the message management unit are displayed on the folder list screen. If the password received by the initial screen display unit is incorrect, message management is performed. It is characterized by having a folder list display section for displaying only folders for which secret setting is not given by the section on the folder list screen.

The mail client program and the mobile phone terminal of the present invention display all folders on the screen when the password accepted by the initial screen display means is correct when the mail client program is started, and when the entered password is incorrect. Causes the processing unit to function as a folder list display means for displaying only folders for which secret is not set on the screen. Therefore, a user who knows the correct password can browse all folders by entering the correct password on the initial screen, but a third party who does not know the correct password can view only the folders that are not set as a secret. Therefore, it is possible to prevent all messages and information from being browsed unconditionally. In addition, the user only needs to input a password even when browsing a folder with a secret setting. If the user does not browse a folder with a secret setting, the password input may be omitted, which makes the operation complicated. Nor.

In addition, the mail client program and the mobile phone terminal of the present invention display all addresses on the screen if the password received by the initial screen display means is correct when the mail client program is started, and set the secret if it is not correct. The processing unit is caused to function as an address book display means for displaying only addresses that have not been displayed on the screen. Therefore, only a user who knows the correct password can browse all addresses, and a third party or a user who omits input can browse only addresses that are not set as secrets.

Hereinafter, the operation of the mail client program 209 will be described with reference to the drawings. FIG. 7 is a flowchart of an operation for starting a mail client program, displaying a folder list, and providing a message for user browsing.

  As shown in FIG. 7, this operation is started by the user operating the UI (User Interface) of the communication terminal apparatus 100 to instruct the activation of the mail client program 209 (ST101). First, the mail client program 209 is started. It is activated (ST102). Subsequently, the mail client program 209 appropriately loads the program from the flash memory 105 to the RAM 104 and performs initialization, and displays the initial screen shown in FIG. 4 (ST103).

  As shown in FIG. 4, an input area for inputting a password and an OK button are displayed on the initial screen, and the user taps the input area to input the password and operates the OK button. When the input is completed, the mail client program 209 can recognize the password. It is preferable to use a character input system for inputting characters using the LCD / touch panel 111 when inputting a password. The operation here will be described with reference to the drawings. When the initial screen is displayed, the user's password input is accepted (ST104), and then it is determined whether the OK button has been tapped (ST105). If it is determined in ST105 that the OK button has not been tapped, the process returns to ST104 to continue accepting password input, and if it is determined that the OK button has been tapped, the process proceeds to steps subsequent to ST106.

  In ST106, the password input by the user is compared with the password stored in the password storage unit 244, thereby determining whether the user has input the correct password. If it is determined in ST106 that the correct password has been entered, all folders provided in the mailbox are displayed on the folder list screen (ST107), and all messages are subjected to browsing processing according to user operations. Provided (ST109). On the other hand, if it is determined in ST106 that the correct password has not been input, only folders to which no secret setting has been assigned are displayed on the folder list screen (ST107), and only messages stored in these folders are viewed. It is used for processing (ST109). The series of operations is thus completed.

  According to the above operations, users who know the correct password can view all folders by entering the password on the initial screen, but third parties who do not know the password enter the correct password on the initial screen. The user cannot view the folder with the secret setting and the message stored in the folder, and cannot know the existence thereof. Further, even a user who knows the correct password can conceal the folder and message to which the secret setting is added by intentionally not inputting the correct password. For example, if a mail client program is started and a correct password is not input before giving the communication terminal device 100 to another person, a specific folder and message can be prevented from being viewed by another person. Furthermore, since the password needs to be input only once on the initial screen displayed at the time of startup, the user's operation is not complicated as in the case where the password is set for each message or folder.

  As described above in detail, according to the present invention, even if the program is started, all messages and information cannot be browsed unconditionally, and access to some messages and information is restricted by an uncomplicated operation. It is possible to provide an e-mail client program that can handle such a problem.

  The present invention is not limited to the above embodiment, and various modifications can be made. For example, in the above operation, if the password entered at startup is correct, all folders and messages can be viewed. If the password is incorrect, the secret folder and message cannot be viewed. Can be applied to the address data managed by the address management unit 223. In that case, if the input password is correct, all addresses can be browsed, and if the password is not correct, the secret-set address cannot be browsed.

  Further, the configuration of the mail client program 209 and the communication terminal device 100 that executes the mail client program 209 of the present invention is not limited to the configuration of the block diagram shown in the above embodiment, and their operations are also described in the above embodiment. It is not limited to the flowchart shown.
